What do you do to keep strong through tough things?

I was looking for ideas on keeping that fortitude going
My sons and I are moving and gosh, so many challenges. We have been working to keep things as mellow as possible because of all the changes including their dad divorcing me. Then my mom is finally understanding we are leaving the area and yesterday she had a meltdown, cut off family relations. It is not easy on my dad who is the eternal peacemaker. I was doing great food wise and went higher than I liked but could have blown it a lot more. Today, though as we have been doing calls, handling things, nothing tastes right and it has been tough eating! Wow, that's a new one for me. This was not to be much real Christmas in terms of any giving rather a time to be with family, loving on them and then say "goodby" for now. guess closure happens different ways. My college sons have not seen this side before; it is opening understanding in new ways. I hate family upsets. seeing me in codependence like I had not realized being before. Yet, there is that side, too, of leaving what I guess I had not realized was bonds and going to where we have our work moving to. A taste of freedom like I had not thought to consider having before. I am blessed that my older son who finishes college in a week and starts an internship in January where we are going and my younger son who is transferring to upper division in what will be our new state is my family. I am lookng I think at being grateful over the family that is not melting down Well, the new year will be a new life, new home, and new work environmnts. At least I am not pregnant Somehow, though, I am surprisingly more desperate(?) to not let weight gain be a problem, too. So what would you do to keep it going....thanks
